--- Comment #3 from Michael Catanzaro <mcatanzaro at igalia.com> ---
The problem is you didn't pass a WebKitWebView property. You're not really intended to create WebKitFindController yourself, but rather to get it from a WebKitWebView using webkit_web_view_get_find_controller().

Anyway, of course we should assert or emit a critical or something instead of crashing. My first instinct would be g_return_val_if_fail(), but there's no place where that would be possible. I guess we could add a g_assert() in webkitFindControllerConstructed, but that's not really a friendly way to signal API misuse. Not sure what we should do here.
